Question

two plane are going with a same speed.they are going to meet in a hour.after travelling 45 minutes they are 200 miles apart.find the total distance

Answer 1

60-45=15 min
distance between two planes is 200 miles
one plane can travel only 100 miles
if time=15 min then distance=100 miles
if time=60 min then
distance=

$\frac{100 \times 60}{15} = 400 \: miles$
total distance= 400×(2 planes)=800 miles
