Question

A CAR COVERS A DISTANCE OF 40 METRE IN 10 secondS. FIND IT'S SPEED IN a) M/ SEC b) KM/HR​

Answer 1

Answer:

Distance covered by car 180 km in 5 hours

(i) Distance covered in 1 hour = \frac{180}{5}=36km

5

180

=36km

Distance covered in 3 hours = 3 x 36 = 108 km

(ii) To cover a distance of 180 km , time taken = 5 hours

To cover a distance of 1 km , time taken = \frac{5}{180}

180

5

To cover a distance of 54 km, time taken = \frac{5}{180}\times54=1.5hours

180

5

×54=1.5hours
