The answer is -15 because -20 plus -10 is -15 and -30 plus 15 is -15
We need to calculate a total TIME.
Let the time required to cover distance d at 20 mph be x. d is the ONE WAY distance, not the total distance traveled (which would be 2d).
Remember the formula d=rt: the distance traveled equals the rate times the time. Here, d = rx, and thus x = d/r = d/(20mph)
Let's begin by recognizing that d(going) = d(returning)
Then (20 mph)x = 6 + (16 mph)x
(20 mph)x - (16 mph)x = 6 miles
Then: (4 mph)x = 6 miles
or: x = 1.5 hours
It takes the bird 1.5 hours at 20 mph to cover distance d, which is 30 miles.
Thus, the total time spent flying is 1.5 hours (going) and [1.5 hours + (6 miles)/(16 mph) returning:
1.5 hours + 1.5 hours + 0.375 hours = 3.375 hours total.
The total distance covered is 2d, or 2(30 miles) = 60 miles.
It took me a while and a lot of experimentation to arrive at these results. Please, if my arguments here are not clear, ask questions.
The ratio of time taken by Henry to time taken by Gavin is 3:5
Step-by-step explanation:
Time taken by Henry for each set = 36 minutes
Time taken by Gavin for each set = 1 hour
We will convert Gavin's time into minutes.
Time taken by Gavin for each set = 60 minutes
Ratio;
Time taken by Henry : Time taken by Gavin
Dividing by 6
Dividing by 2
The ratio of time taken by Henry to time taken by Gavin is 3:5
Keywords: ratio, division
