Option 1
1. The Speed of the bus in Km/h is
1 point
O (A) 4
O (B) 5
O (C) 60
O D) 20
2 What is the ratio of one​

Answer 1

answer is 60

as manju and sanju are going by bus

20+40 = 60.

Answer 2

Given :-

Walking distance covered 40 time taken 10

Cycle distance covered 100 time taken 20

Car distance covered 600 time taken 10

Bus distance covered 500 time taken 25

(Refer to image also)

To Find :-

1) The speed of the bus in km/h ?

2) The ratio of speed of the car and the cycle ?

3) Which mode of transport has the fastest speed ?

Formula used :-

• Speed = Total distance covered / Total time taken .

Solution :-

Walking :-

→ Total distance covered = 40 km

→ Total time taken = 10 hours

So,

→ Walking speed = Total distance covered / Total time taken = 40/10 = 4 km/h

Cycle :-

→ Total distance covered = 100 km

→ Total time taken = 20 hours

So,

→ Cycling speed = Total distance covered / Total time taken = 100/20 = 5 km/h

Car :-

→ Total distance covered = 600 km

→ Total time taken = 10 hours

So,

→ Car speed = Total distance covered / Total time taken = 600/10 = 60 km/h

Bus :-

→ Total distance covered = 500 km

→ Total time taken = 25 hours

So,

→ Bus speed = Total distance covered / Total time taken = 500/25 = 20 km/h

then,

1) Speed of bus in km/h is equal to 20 km/h .

2) Speed of car : Speed of cycle = 60 : 5 = 12 : 1 .

3)

→ 60 km/h > 20 km/h > 5km/h > 4 km/h

→ Car > Bus > cycle > Walk .

Car is the mode of transport that has the fastest speed .
