On transposing numbers or variables,
- Plus changes to minus.
- Minus changes to plus .
- Multiply changes to divide.
- Divide changes to multiply.
You just have to multiply straight across. Multiply the numerators for the new numerator, and the denominators for the new denominator.
5*3=15
4*8=32
15/32 is the answer (b).
The speed of the jet stream is 4.55 miles per hour
Step-by-step explanation:
Distance of one way trip= 3000 miles
The total distance of the round trip= 6000 miles
Total time = 11 hrs
Speed of the plane = 550 miles per hr
Speed = distance/time
= 6000/11
= 545.45 miles per hour
Speed of the plane = 545.45 + speed of the jet stream
550 = 545.45 + speed of jet stream
Speed of jet stream = 4.55 miles per hour
The speed of the jet stream is 4.55 miles per hour
