a) Nairobi 400 km Kisumu
Speed = 120 km\hr
Distance 400 km
Time taken = $\frac{400}{120}$
= 3 hrs 20 minutes
= 8.30 + 3 hrs 20 minutes
= 11.50 a.m
The car arrived in Nairobi
At 11.50 a.m
b) At 8.30 a.m distance covered by bus
= $\frac{1}{2}$ x 80 = 40 km
Distance left = 360 km
speed = 200 km\hr
Time taken to meet
= $\frac{360}{120}$ = 1 hr 48 minutes
they met at
8.30
+ 1.48
10.18 am
c) 8. 00 to 10.18 am
= 2 hrs 18 min
Distance
= 2 x 80 + $\frac{18}{60}$ x 80
= 160 + 24 = 184 km from Nairobi
