MULTIPLE CHOICE QUESTION

If distance = rate x time, which of the following must also be true?
Rate = distance x time
Time = distance/rate
Distance = rate/time
Time = rate/distance
Answer explanation
From the formula distance = rate x time, we can rearrange it to find time. Dividing both sides by rate gives time = distance/rate, making this the correct choice. The other options do not correctly represent the relationship.

If a train travels at a speed of 100 km/hr, how far will it travel in half an hour?
100 km
50 km
25 km
10 km
Answer explanation
To find the distance traveled, use the formula: Distance = Speed × Time. Here, Speed = 100 km/hr and Time = 0.5 hr. Thus, Distance = 100 × 0.5 = 50 km. Therefore, the correct answer is 50 km.

If a jogger runs a 10-kilometer race in 60 minutes, what is her average speed?
10 km/hr
5 km/hr
6 km/hr
1.66 km/hr
Answer explanation
To find the average speed, divide the distance by the time. The jogger runs 10 kilometers in 60 minutes, which is 1 hour. Thus, average speed = 10 km / 1 hr = 10 km/hr, making the correct answer 10 km/hr.

If a car travels at 40 km/hr for 4 hours, how much distance has it covered?
160 km
140 km
120 km
100 km
Answer explanation
To find the distance covered, use the formula: Distance = Speed × Time. Here, Speed = 40 km/hr and Time = 4 hours. Thus, Distance = 40 × 4 = 160 km. Therefore, the correct answer is 160 km.

An aircraft carrier travels a distance of 1,000 km in 3 days. What is its average rate of speed?
1,000 km/hr
3,000 km/hr
333.3 km/hr
13.9 km/hr
Answer explanation
To find the average speed, divide the total distance by the total time. Here, 1,000 km / 72 hours (3 days) = 13.9 km/hr. Thus, the correct answer is 13.9 km/hr.

A train leaves New York traveling at a speed of 90 km/hr. How much distance will it cover in five hours?
45 km
450 km
180 km
18 km
Answer explanation
To find the distance covered, use the formula: Distance = Speed × Time. Here, Speed = 90 km/hr and Time = 5 hours. Thus, Distance = 90 km/hr × 5 hr = 450 km. Therefore, the correct answer is 450 km.

If a train travels 1,600 km in 16 hours, how fast is it moving?
60 km/hr
100 km/hr
120 km/hr
90 km/hr
Answer explanation
To find the speed, divide the distance by time: 1600 km ÷ 16 hours = 100 km/hr. Therefore, the train is moving at 100 km/hr.
