An aeroplane flew from Qatar to Bahrain. The distance flown was 135 km. The average speed was 180 km/h. Work out the time taken. Give your answer in minutes

Given:

The distance flown was 135 km.

The average speed was 180 km/h.

To find:

The time taken by the airplane.

Solution:

We know that,

Putting Distance = 135 and Speed = 180, we get

The time taken by the airplane is 0.75 hours.

We know that,

1 hour = 60 min

0.75 hour = 0.75 × 60 min

0.75 hour = 45 min

Therefore, the time taken by the airplane is 45 min.

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
