Question

3. Rohit is driving his car at a speed of 42 km/h. Find the distance covered by him in 42 min.​

Answer 1

Answer:

29.4 km.

Step-by-step explanation:

Speed of car = 42 km/h

Time = 42 min

= 42 / 60 hours. ( 1 min = 1/60 hours)

= 7 / 10 hours

Now, Distance = Speed × time

= 42 × 7 / 10

= 29.4 km

Therefore, the answer is 29.4 km.

Answer 2

Question :-

Rohit is driving his car at a speed of 42 km/h. Find the distance covered by him in 42 min.

_____________________________________

Given :-

• Rohit is driving his car at a speed of 42 km/h.

_____________________________________

To find :-

• the distance covered by him in 42min

______________________________________

Formula :-

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

______________________________________

Solution :-

speed of car = 42km/Hr

time = 42min

$\rm :\longmapsto\: \frac{42}{60h} (1min \: = \frac{1}{60h})$

$\rm :\longmapsto\: \frac{7}{10}hours$

now according to question,

distance = speed × time

$\rm :\longmapsto\:42 \times \frac{7}{10} = 29.4km \\ \\ \rm :\longmapsto\:d = 29.4km$

so therefore the distance covered by him in 42min is 29.4km
