Answer 1

q1.a.108km/hr=80*1000÷60*60=30m/ s
b.95 m/ s=95*60*60/1000=342km/hr

q2. speed= distance/time
80=d/5
d=80*5
=400km

speed=distance/time
=400/4
=100km/hr

speed =distance/time
50=400/t
time=400/50
=8hr

Q3. 18km/hr= 18*1000/60*60=5 m/s
6m/s is greater

54km /hr= 15m/s
18m/s is greater

q4. no speed is inversely proportional to time if speed increases, time decreases and vice versa.

Q5. speed= 90/1.5=60km/hr
speed=90/1=90km/hr
speed= distance/time
45= 90/t
time= 90/45=2hr
