Question

its a question of direct and inverse proportion
The speed of a bus is 45km/hr. Find the distance travelled in 110 min.Is it direct or inverse proportion??

Answer 1

Find the distance:

Speed = 45 km/hour

1 hour = 45 km

60 mins = 45 km

1 min = 45/60 = 0.75 km

110 mins = 0.75 x 110 = 82.5 km

The distance is directly proportional to the time.

⇒ More time spent will lead to more distance traveled.

Answer: (a) 82.5 km  (b) directly proportion

Answer 2

$given \\ speed \: = 45kmhr \\ to \: find \: distance \: in \: 110min \\ \\ 1hr = 60min \\ 1min = \frac{45}{60} \\ 1min = 0.75 \\ so \\ 0.75 \times 110 \\ = 82.5km \\ \\ its \: also \: called \: unitary \: method$
