Question

A car is 35 km towards the north. After 20 minutes, it is 75 km towards the south.
Find how much distance it will cover in one hour?

Answer 1

Answer:

Correct option is 25

Step-by-step explanation:

Speed of car in first 15 minutes = 40 km/h

Distance covered = speed × Time taken

60 minutes = 1 hour

15 minutes =

60

15

hour

Distance covered = 240×

60

15

=10km

Speed of car in next 15 minutes = 60 km/h

Distance covered = 60×

60

15

=15km

∴ Total distance covered = (10+15)km = 25 km

∴ 25 km is correct

Answer 2

Answer:

The car will cover distance of 105 Km in one hour.

Step-by-step explanation:

Given, a car travelled distance towards the north = 35 Km

The distance of 35 Km covered in 20 minutes then car moves in south direction.

We can calculate the speed of the car from the distance traveled in given time.

Here, distance = 35 Km

Time taken = 20 min

The speed of the car = distance/time

Speed of the car $=\frac{35}{20}=1.75\;km/min$

Now, Distance covered = Speed × Time

Distance covered in 60 min = 1.75 × 60 = 105 Km

Therefore, the distance covered in the one hour will be equal to 105 Km.
