**Answer This Question**

Pls help. Tks

dist. betw. P & Q is unknown

David

speed: 80 km/h

time: 3h 40 min = 3 2/3 h

dist. moved = 293 1/3 km

Saul

speed: 96 km/h

time: 3h 20 min = 3 1/3 h

dist. moved = 320 km

so

dist. betw. P & Q is 613 1/3 km

time taken by David to reach Q

= 613 1/3 ÷ 80 = 7 2/3 h

= 7 h 40 min

time reach Q is 4. 40 p.m.
