Question

if a car travels 60 km in an hour, how far will it travel in (1) 2 hours? (2) 15 minutes? (3) half an hour? (4) three and a half hours?​

Answer 1

Answer:

2 hour=180 km

15 minutes=15 km

half an hour=30 km

Answer 2

Given:

• A car travels 60 km in an hour.

To Find:

• what is the speed and (1) 2 hours (2) 15 minutes (3) half an hour (4) three and a half hour.

Solution:

Here, distance of car is given 60 km and time is also given 1 hour and firstly we have to find speed.

As we know that,

$\large{\sf{\fbox{\green{Speed = {\frac{Distance}{Time}}}}}}$

Now,solve the question

$\: \: \sf \leadsto \: speed = \frac{60}{1} = 60 \frac{km}{hr}$

Now, after finding the speed we have to find distance

(1)2 hours

As we know that,

$\large{\sf{\fbox{\red{Distance = Speed ×Time}}}}$

Now,solve the question

$\: \: \sf \red \leadsto \: distance = 60 \times 2 = 120km$

Now,find the distance

(2)15 minutes

$\: \sf \:60 \: minutes = 1 \: hour \\ \\ \: \sf \: 15 \: minutes = \frac{60}{15 } \\ \\ \: \sf \: = 4 \: hour$

$\: \: \sf \green \leadsto \: distance = 60 \times 4 = 240 \: km$

Now,again find distance

(3)Half an hour

$\: \: \sf \purple \leadsto \: distance = 60 \times \frac{1}{2} = 30 \: km$

Now,again find distance

(4)Three and a half hour.

$\: \: \sf \pink \leadsto \: distance = 60 \times \frac{13}{4} = 195 \: km$
