Question

Flying the SR-71A jet, Capt. Elden W. Joersz, USAF, set a record speed of 2193.16 miles per hour. At this speed, the algebraic expression 2193.16t gives the total distance flown in t hours. Find the distance flown by the SR-71A in 1.7 hours.

Answer 1

The required distance is 3728.372 miles.

Explanation:

Step 1

The distance flown is t hours given by:

2193.16t

Step 2

Let distance be represented by d, thus:

d = 2193.16t

Step 3

d = 2193.16t

Substitute t = 1.7 in the relation:

d = 2193.16 x 1.7

Step 4

Solve for d:

d = 2193.16 x 1.7

d = 3728,372
