Question

A motorbike covers 76.5 km distance in 1.5 hours. How much distance does the motorbike covers in 3.5 hours?​

Answer 1

Answer: 178.5 km.

Step-by-step explanation: Given:

Distance covered by the motorbike — 76.5 km.

Time taken to cover 76.5 km — 1.5 hours.

__________________________________________________________

Therefore, we will find the distance covered in 1 hour and multiply it by 13.5 (unitary method)

Distance covered in 1 hour — $\frac{76.5}{1.5}$  = 51 km.

Distance covered in 13.5 hours = Speed x Time

                                                    = (Distance covered in 1 hour) x (3.5)

                                                    = (51) (3.5) = 178.5 km,
