alex has a 48 mile trail first half of the time he was biking twice as fast as the second half of the time if he spent 4 hours on the road how fast was he biking at first

16 mph

Step-by-step explanation:

Givens:

4 hours total time

48 miles total distance

So our equation should look like this.

48 = 2x(2) + x(2)

Where x = speed second half of trip.

x = 8

x*2 = 16 mph

the distance between point a and point b is 6 units

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.
