How do you evaluate variable expressions? Given: the total distance traveled by boat 1 hour upstream and 30 minutes downstream in which the rate of current is 3kph. The total distance travelled by a boat 1 hour upstream and 30 minutes downstream in which the rate of current is 3 kph: (r + 3) + (r - 3) 6. trip a 40 kph und for the other half the distance of 60 kph: What is his average speed for the entire trip?. The total distance traveled will be d kms. How fast did each walk? A, Q:8. Then he reduced his speed to 60km/h. How do you simplify the expression #3x-x+4#? A scrambled word: 2021-01-19: From john: Java Data Type: Exercise-7 with Solution. 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.
