riya and priya set on a journey . riya moves eastward at a speed of 25 kmph and priya moves westward at a speed of 40 kmph . how far will be priya from riya after 15 minutes
"total eastward distance = 25 kmph * 1 / 4 hr = 6.25 km total westward distance = 40 kmph * 1 / 4 hr = 10 km total distn betn them = 6.25 + 10 = 16.25 km ans 16 km answer : b"
multiply(speed(add(25, 40), const_60), 15)
