Question

A car completes a journey in 2 hours. Its average speed over this journey was 45 mph. Calculate the distance travelled by the car in miles.

Answer 1

90 miles

Explanation:

• It is given that a car completes journey in a amount of time with a specific average speed.
• Average speed is defined as the total distance covered by the car in the given total time.

• The distance travelled by the vehicle is given by relation,$d=average speed *time$
• it is given that the time is 2 hours and the average speed as 45 mph.
• So by substituting we get $d=2*45$
• $d=90miles$
• Hence the car completes a distance of 90 miles in 2 hrs.

Answer 2

Given,

Total time of the journey = 2 hours

The average speed of the car in the journey = 45 miles/hour

To find,

Total distance traveled by the car in miles.

Solution,

We can simply solve this numerical problem by using the following process:

Mathematically,

speed (s) = distance traveled (d)/time of journey(t)

=> Distance traveled (d) = speed (s) x time of journey(t)

Now,

Total distance traveled by the car

= speed (s) x time of journey(t)

= 45 miles/hour x 2 hours

= 90 miles.

Hence, the car covered a total distance of 90 miles.
