Yearly compound interest is given by the following formula:

A is the total amount after the time period elapses. P is the initial amount invested. r is the interest rate in decimal form, and t is the amount of years that elapse.
The interest rate is 1.5%. Divide by 100 to convert into a decimal:

Answer:
400mph and 465 mph
Step-by-step explanation:
let the speed of first plane be x
speed of 2nd plane = x+65
dist travelled by first plane in 2 hrs = 2x
dist travelled by 2nd plane = 2(x+65)= 2x+130
when they meet, the sum of dist travelled by them is 1730
4x + 130 = 1730
4x = 1600
x = 400moh
x+65 = 465 mph
