Question

A car can cover 275 km in 5 hours. If its speed is reduced by 5 km/h, then how much time will the car take to cover a distance of 250 km?

• A. 5 hr
• B. 5 hr 30 min
• C. 4 hr 30 min
• D. 6 hr

Answer 1

Answer:

A. 5 hr

First, find the original speed.

Distance = 275 km
Time = 5 hours
$\text{Speed} = \frac{275}{5} = 55 \text{ km/h}$
Speed reduced by 5 km/h:

$55 - 5 = 50 \text{ km/h}$

Now find the time to cover 250 km at 50 km/h:

$\text{Time} = \frac{250}{50} = 5 \text{ hours}$

The car will take 5 hours.
