7.3.5h

8.5.333h

calculate speed

9.25km/h

10.5km/h

explanation

1.Distance=SpeedxTime

or D=ST

Given:

D=?

S=25km/hr

T=2hours

D=25(2)

D=50km/h

3.1 1/2 hour us (60+30)=90 minutes

D=ST

D=45(90)=4050

1m=1000km

4050/1000=4.05 km/h

5.1/2 hour=60 minutes

GiVen=

d=?

s=90km/h

t=1/2h

d=st

d=90(60)=5400

1m=1000km

5400/1000km=5.4km/h

TIME

1.t=d/s

given:

d=90km

s=20km/h

t=?

t=90/20

t=4.5 or 4 1/2 hour

SPEED

s=d/t

s=200/8

s=25km/h
