Speed is determined as distance travelled over time. In the
problem, given is the speed and distance. Time, we will be distance over speed.
Substitute the given to the formula
t=d/s
t = 200 km / 35.27 km/h
t = 5.67 hours
Answer:
sets the size of the drawing paper. For size A drawing paper
B r = 178 + h;
b r + h = 676;
then, 178 + 2h = 676 => h = 498/2 = 249 => b r = 178 + 249 = 427;
