Question

A car covers 310 km in 5 hours. How much time will it take to cover 403 km?
​

Answer 1

Answer:

The time take by the car to cover 403 km is 6.5 hours or 6 hours 30 minutes.

Step-by-step explanation:

Here, we know that the distance is 310 km.

The time taken by the car to cover 310 km = 5 hrs.

Therefore the speed will be = D/T

= 310 / 5

= 62 km/hr

Therefore, the time taken by the same car to cover 403 km at the same speed = 403 / 62

= 6.5 hr or we can say that 6 hrs 30 mins.

Hope it helps you!

Answer 2

Given: Distance covered by car in 5 hours = 310 km

To find: Time it will take to cover 403 km

Assumption: The car is travelling at a uniform speed.

Solution: According to the given question,

Time taken to cover 310 km = 5 hours

Using the formula for speed,

.: Speed = $\frac{Distance}{Time}$

Distance = 310 km, Time = 5 hours

Speed = $\frac{310}{5}$ = 62 km/h

Now, we need to find time the car will take to cover 403 km distance at the speed of 62 km/h

.: Speed = $\frac{Distance}{Time}$

.: Time = $\frac{Distance}{Speed}$

          = $\frac{403}{62}$ = 6.5 hours

The car will take 6.5 hours to cover the distance of 403 km.
