Question

A car travels 210 km in 3 hours. How far does
it travel in 30 minutes ?
​

Answer 1

Answer:

35

Step-by-step explanation:

First, we have to find how much kilometer a car can travel in 1 hour=70

now it shows 30 min, which is the half of 1 hr. so, 70÷2=35

∴a car can travel 35 km in 30 mins.

Hope it helps

Answer 2

$speed \: = \frac{distance}{time}$

$speed = \frac{210}{3} = 70 \: km \: {hr}^{ - 1}$

$distance = speed \times time$

$distance = 70 \: km \: {hr}^{ - 1} \times \frac{1}{2} \: hr$

$distance = 35 \: km$
