D.They have Indonesian ancestry. 60 kph. 5% annual interest rate 4. the distance traveled by a man driving at . , Step 2: Identify the given. Now try one by yourself. Aku 2021-11-27 23:22:17 @Mike Depends on how fast that actually is. Therefore we can substitute 2w for l in the equation for the perimeter giving: p = 2*(2w) + 2w For this problem we are also told the perimeter is 3*13.7 which is 41.1 so we can substitute 41.1 for p . Therefore, the equation to be solved is: 55(t) + 40(2.5 t) = 130 55t + 100 40t = 130 100 100 15t 15 = 30 15 t = 2 55 ( t) + 40 ( 2.5 t) = 130 55 t + 100 40 t = 130 100 100 15 t 15 = 30 15 t = 2 This means that the time spent travelling at 40 km/h was 0.5 h.
