Detailed Solution
Download Solution PDFరోవర్ వేగం x మరియు నీటి ప్రవాహ వేగం y అనుకుందాం.
ఎగువకు వెళ్లడానికి వేగం = (x –y)
⇒ 40/ (x – y) = 8
⇒ x – y = 5 ---- (1)
దిగువకు వెళ్లడానికి వేగం = (x + y)
⇒ 40/ (x + y) = 5
⇒ x + y = 8 ----(2)
సమీకరణం 1 మరియు 2 నుంచి
x = 6.5 కి.మీ/గంట
∴ రోవర్ వేగం = 6.5 కి.మీ/గంటLast updated on Jul 5, 2025
