A plane flies at a steady rate of 40 mph while a second plane flies at a steady rate of 100 mph. The planes are 200 miles apart
Brums [2.3K]

Answer:

1\ \text{hour}\ 25\ \text{minutes and }12\ \text{seconds}

Step-by-step explanation:

The combined distance that both planes will cover is 200 miles

Time taken by both planes will be the same (t)

\text{Distance}=\text{Speed}\times \text{Time}

So, the combined distance is

40t+100t=200\\\Rightarrow 140t=200\\\Rightarrow t=\dfrac{200}{140}\\\Rightarrow t=1.42\ \text{hours}=1\ \text{hour}\ 25\ \text{minutes and }12\ \text{seconds}

They will meet in 1\ \text{hour}\ 25\ \text{minutes and }12\ \text{seconds}.
