An airplane maintains a speed of 630 $\mathrm{km} / \mathrm{h}$ relative to the air it is flying through as it makes a trip to a city 750 $\mathrm{km}$ away to the north. ( a) What time interval is required for the trip if the plane flies through a headwind blowing at 35.0 $\mathrm{km} / \mathrm{h}$ toward the south? (b) What time interval is required if there is a tailwind with the same speed? (c) What time interval is required if there is a crosswind blowing at 35.0 $\mathrm{km} / \mathrm{h}$ to the east relative to the ground?

Step 1
0 km/h toward the south, the airplane's effective speed relative to the ground will be the difference between its speed relative to the air and the headwind speed. So, the effective speed is: $630 - 35 = 595 \ \mathrm{km/h}$ Show more…
